JAMES NEVMON, OF SKIPPERVILLE, ALABAMA.

PLOW-COLTER.

SPECIFICATION forming part of Letters Patent No. 424,897, dated April 1, 1890.

Application iiled October 31, 1889. Serial No. 328,797. (No model.)

To all whom. it may concern:

Be i't known that I, JAMES NEWMON, a citizen of the United States, and a resident ot Skipperville, in the county of Dale and State of Alabama, have invented certain new and useful Improvements in Plow-Colters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and

to letters of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a representation of this invention and is a side view. Fig. 2 is a front View. Fig. 3 is a rear view.

This invention relates to colters for plows; and it consists in the novel construction and combination of parts, ashereinafterdescribed, and pointed out in the claim.

The object of the invention lis to construct a colter for plows wherein the heel-pin shall be formed integral with the colter for securing the latter with the plowshare to the foot of the plow-stock.

In the accompanying drawings, theletter A indicates the colter, which is triangular in shape, having an upper curved cutting-edge b and a horizontal broad base o. The base c of the colter is made broadest in its middle portion to afford a bearing for the heel-pin B, which, extends in a rectangular form a certain distance from the colter to engage in a corresponding` rectangular bearing through the plowshare and the foot of the stock, as shown. The end of the heel-pin which projects through the rear of the plow-stock is threaded to engage a nut C for securing the plow and colter to the stock D.

the colter taper from the base to the cuttingedge upward, forward, and downward, the Swell being in the middle and rear portion The sides of near the heel-pin. The colter is secured vertically to the plowshare E, and its cuttingedge is curved from above downward, its eX- treme point d bearing upon the face of the shovel near its entering end. Above this bearing-point is an arched notch in the rear edge of the colter,which is designed to span any uneven or irregular portion of the surface of the plow-plate, so that the point of the colterwill bear firmly against said plate. The rear of the base c,which is secured to the shovel and plowstock by the heel-pin, projects beyond the rear of the shovel, as at g, and rests against the upper surface of the plow-stock, so that an eifective support is aorded. It will be observed that by the disposition of the colter with its broad base resting upon the plowshare and the plow-stock, the assembled parts being bound together by a single substantial fastening and mutuallysupporting each other, it is eminently tted to operate inV cutting through such obstructions as roots and weeds without straining one partmore than another.

What I claim, and desire to secure by Let'- ters Patent, is-

The colter for plows of the form shown and described, having a swell in its middle rear portion, from which it tapers forward and downward to its curved cutting-edge, the

bearing-point at the lower end of said cuttingedge, the notch in the rear edge above said bearing-point, and the heel pin or bolt, in combination with and securing a shovel to a plowstandard, substantially as specified.

In testimony 'whereof I affix my signature in presence of two witnesses.
